ESP8266 GPIO Expansion Board Screw Terminal Adapter

The ESP8266 GPIO Expansion Board Screw Terminal Adapter is designed to simplify the connection of external devices to the ESP8266 microcontroller board. This adapter serves as an interface between the ESP8266 and various sensors, actuators, or other electronic components, providing a convenient and secure method for wiring connections.

  Key Features:  

• Compatibility: Fully compatible with ESP8266 ESP-12E modules.
• Expansion Capability: Each GPIO pin of the ESP8266 can be expanded to two terminals, allowing for easier reuse of pins in large-scale smart home or IoT projects.
• Dual Connection Methods: Offers both Pin Header Connectors and Screw Terminals, giving users the flexibility to choose the most suitable connection method for their needs.
• Double-layer Board: Features a double-layer PCB design, with each pin wired on both sides for enhanced connectivity.
• Ease of Use: Pre-assembled, no need for additional soldering, making it ready to use out of the box.

  Specifications:  

• Board Type: GPIO Expansion Board with Screw Terminal Adapter
• Compatibility: ESP8266 ESP-12E
• Connection Methods: Pin Header Connector & Screw Terminal
• PCB Design: Double-layer

  Package Includes:  

• 1 x ESP8266 GPIO Expansion Board Screw Terminal Adapter

  Usage Instructions:  

• Connection Setup: Choose your preferred connection method (Pin Header or Screw Terminal). For screw terminals, loosen the screws, insert the wires from your external devices, and tighten the screws to ensure a secure connection.
• Mounting: Attach the expansion board to your ESP8266 module by aligning the headers and pressing them together.
• Wiring: Connect your external devices such as sensors, actuators, or other electronic components to the screw terminals corresponding to the GPIO pins you wish to use.
• Programming: Use the appropriate GPIO pin numbers in your ESP8266 program to interact with the connected external devices.

This GPIO Expansion Board Screw Terminal Adapter is an excellent tool for anyone looking to expand the connectivity options of their ESP8266 module, making it ideal for complex projects requiring multiple GPIO connections.
